/**
 * PWA route smoke tests — post-rip-out (2026-05-16).
 *
 * The PWA layer was removed because it produced recurring reload-loop
 * bugs (admin dashboard, deploy pill, admin-screen flash). The routes
 * still exist but serve self-unregister bodies so any browser with the
 * old SW installed auto-recovers. The layout no longer registers a SW.
